MACHINE FOR UNITING WELTS OR R'ANDS TO SOLES OR HEELS.

SPECIFICATION forming part of Letters Patent No. 611,405, dated September 27, 1898 Application filed April 1 6 1 18 9 '7.

To all whom it may concern:

Be it known that I, LoUIs A. CASGRA IN, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Machines for Uniting Welts or Rands to Soles or Heels, of which the following description, in connection with the accompanyin g drawings, is a specification, like letters on the drawings representing like parts.

In this machine a sole or heel to receive a welt or a rand is laid on a spring-supported table, which is rotated intermittingly by a long vertical pinion, so that the table may occupy any position required to adapt it to the thickness of the sole or heel. The welt or rand being applied to the sole or heel is acted upon by a feeding device (shown as a wheel) which has a surface speed a little faster the tendency of the feeding device is to crowd the welt forward to thus enable said welt to be fed, as it were, a little faster in order that it may be crimped or adapted to lay upon the sole and assumes the outline which the welt must take. The welt is controlled by a weltfeeding guide composed of a bottom plate on which the under side of the welt rests and a pressure-finger acting on the top or upper side of the welt, said pressure-finger having teeth which enter the top side of the welt. The welt-guide is moved back and forth or toward and from the driver, as herein shown, in a horizontal circle, it riding backward over the welt or rand after each nail has been driven into the welt or rand, and at such time the teeth of the lever scrape over the top of the welt or rand; but just before another nail is driven the welt-guide is moved horizontally in the opposite direction, the teeth of the lever then entering the welt or rand, thus feeding or crowding it toward an edge gage and the last nail which was driven, such action enabling the welt or rand to be put onto the sole or heel without objectionable tension and enabling it to be bent as required to the curved outline of the sole or heel. The weltguide is moved away from the nailing-point by the swinging motion of the hub, in which is Serial No; 632,465. (No model.)

mounted the strip-carrier, and it has given to it its feeding movement by a suitable spring.

Figure 1, in side elevation, shows a sufficient portion of a nailing-machine with my improvements added to enable my invention to be understood. Fig. 2 is a detail to be referred to. Fig. 3 shows a part of the apparatus for carrying the welt-guide; Fig. 4, a front elevation of the work support or table and the welt-guide; Fig. 5, a side elevation thereof on a somewhat larger scale than shown in Fig. 1; Fig. 6, atop or plan view of the parts shown in Fig. 4, with part of a sole and welt or rand; Fig. 7, a section in the dotted line m, Fig. 6; and Fig. 8, a section on the dotted line 00, Fig. 6.

The standard A, on which rests the head A, the main shaft A provided with a friction clutch-pulley, the pinion B fast on shaft A and engaging gear B fast on shaft 13, provided with cams B and B the lever O actuated by cam B and provided at one end with sector-teeth C the hub C, having the arm O and depending arm 0, carrying a hub 0 in which is placed a rotary reciprocating strip-carrier, it deriving its movement from the sector-teeth C the strip-carrier containing a metallic strip S, the lever C for sliding the hub C and strip-carrier longitudinally, the driver-bar B, the driver I), the arm f for actuating the cutters, and the slide-rod A for controlling the clutch-pulley, and the hollow hub A and rib A of the'column A are and may be all as shown and designated by like letters in United States Patent No. 490,625, dated January 24, 1893.

To this well-known machine I have added certain parts, which I will now describe.

' I have provided a stand aof irregular shape and have secured it by a bolt a to an adj ustable block a confined to the standard. This stand has bearings a for a rod a surrounded by a spiral spring a, one end of which is seated on one of the said bearings, while its opposite end acts on a shoulder a and lifts saidrod with its attached work support or tabled, provided, preferably, on itsupper side with a series of sole engaging teetha and at its edge with gear-teeth a The rod a in 'practice has its lower end connected with a treadle (not shown) located at the floor, so that when desired the operator may depress the Work-support for the introduction or removal of the work, the depression of the work support for this purpose drawing down the rod (0 and lifting the pressing-finger b of the Welt-guide from the welt and above the bottom part b of said guide. The teeth (1/ are engaged by the teeth of the long pinion 6 mounted in a tubular part b of the stand a, the upper end of the said long pinion having bevel-teeth b, which are engaged by the bevel-teeth b fast on a feeding device or wheel b, having, preferably, a series of teeth b to act on the welt or rand w, lying on the sole w, or it might be a heel. (Not shown.) This work-support is adapted to rise and fall to adapt it to any variations in thickness of the sole and welt or rand or of a heel, and the use of this long pinion enables the worksnpport to be rotated intermittingly, no matter what the thickness of the material lying on the work-support under the feeding device or usual nose of the machine, through which each nail or fastener is driven. This feedwheel is fixed on a shaft 0, mounted in the bearing of the stand a.

The shaft 0 has a threaded portion 0 on which is screwed a ratchet-wheel 0 which is adapted to be engaged, when said shaft is to be moved, by a pawl 0 pivoted on a pawlcarrier 0 having a sleeve-like hub o which surrounds the shaft 0 loosely, the said sleeve being toothed externally, (see Fig. 6,) said teeth being engaged by a toothed rack 0 fast on the hub O and extended under the said sleeve. (See Figs. 1 and 2.)

The stand a has an ear 6?, and a stud d held at its lower end in said ear, receives on it the hub d of a welt-guide frame 01 it being provided with a projecting portion Z), which constitutes the lower arm of the weltguide.

The frame (1 has ears d provided with a pin 01 on which is mounted a sleeve or tube 01 carrying at one end the welt-pressing finger b having inclined teeth 12 to enter the upper side of the welt or rand. The opposite end of said sleeve has an arm or extension cl, provided with a hole through which the rod a is passed, it having at its upper end a head to act on the said arm, the said arm having a second projection d ,which is acted upon by a suitable spring 02 which normally acts to keep the pressing-finger b down on the welt or rand lying on the bottom plate I), and the teeth b entering the welt or rand.

The frame cl has a projection e, acted upon by a spring 6, which normally acts to swing the said frame about the stud CV and keep the bottom plate 6 of the welt-guide against the edge gage c connected by screw Q with the stand a, said edge gage also acting as a shield to cover the long teeth of the pinion b the said frame having a stud-screw c, which is struck by the hub 0 each time that the arm 0 and the hub C are swung about the shaft A as provided for in said patent. When the hub (J meets the end of said studscrew, the welt or rand guide is moved back away from the driver, the teeth 17 then dragging over the welt or rand, and as the hub G is returned or moved away from the said studscrew the spring 6 acts to move the weltguide toward the driver, the teeth Z1 at such times entering the top of the welt or rand and acting on the same to push the outer edge of said welt or rand against the edge gage and to crowd it up toward the last nail driven into the welt or rand to unite it to the sole or heel. In this way the welt or rand may be put onto the sole and so laid as to conform to any curvature of the edge of the sole, and any unusual stretch in the welt or rand is also taken out.

The surface speed of the feeding device is a little faster than the surface speed of the work-support, so that the action of the feeding device on the welt or rand tends to crowd or feed it up against the said edge gage and the point Where the last nail is driven into the welt or rand.

The teeth a by engaging the sole or heel prevent undue slipping of the sole or heel on the work-support.

By the term welt, as referred to in the claims, I also intend to include its equivalent, a rand, and by the term sole I mean also to include a heel.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a nailing-machine, a vertically-mow able, loosely-supported table to sustain the work; a toothed gear located below said tableand operatively connected therewith a longtoothed pinion occupying a position substantially parallel .to the center of rotation of said table; means to rotate said longtoothed pinion that it may rotate said table in unison with it and yet let said table rise and fall to adapt itself to any variation of thickness of the material lying upon it and between it and the feeding device employed to move the material over the surface of said table, substantially. as described,

2. The spring-sustained work-support having an attached gear, a long pinion having its teeth in engagement with the teeth of the said work-support and provided with bevelteeth at one end, and a feeding-wheel having bevel-teeth engaging the bevel-teeth of the said long pinion, combined with a shaft and means to rotate it, the said feed-wheel, and the said work-support, substantially as described.
